Question
Which of the following statement is true? (Pick the best answer)sequence <B F K C> can involve more than 4 itemsitemset {B, F, K, C} can have more than 4 itemsAll of the aboveNone of the above
Solution
The best answer would be "itemset {B, F, K, C} can have more than 4 items".
Here's why:
-
A sequence <B F K C> is an ordered list of items. In this case, it has exactly 4 items - B, F, K, and C. Unless more items are added to it, it cannot involve more than 4 items.
-
An itemset {B, F, K, C} is a set of items. In this case, it also has exactly 4 items - B, F, K, and C. However, unlike a sequence, an itemset is not ordered, and more items can be added to it, so it can have more than 4 items.
Therefore, the statement "itemset {B, F, K, C} can have more than 4 items" is true, while the statement "sequence <B F K C> can involve more than 4 items" is not. So, the best answer is "itemset {B, F, K, C} can have more than 4 items".
